Subject: Maintainability Allocation
Message:
During reliability allocation, I understand that I need to know each component quantity. But for maintainability allocation, do I need this quantity. For example, there’s 4 wheels on a car, if I lost one wheel, I can allocate its MTTR, but if I take in account the 4 wheels, the MTTR will increase, but, in fact, for each wheel I must have the same MTTR. I made a simulation and I find, say, ½ hour for a wheel, but with the quantity 4, I find ¾ hour. So do I must take in account the quantity for the same component for maintainability allocation.
